<h2 id="synopsis">Synopsis</h2>
<p>Show if you can migrate the database(s) between the servers.</p>
<h2 id="description">Description</h2>
<p>When you want to migrate from a higher edition to a lower one there are some features that can't be used.<br />
This function will validate if you have any of this features in use and will report to you.<br />
The validation will be made ONLY on on SQL Server 2008 or higher using the 'sys.dm_db_persisted_sku_features' dmv.</p>
<p>This function only validate SQL Server 2008 versions or higher.<br />
The editions supported by this function are:</p>
<ul>
<li>Enterprise</li>
<li>Developer</li>
<li>Evaluation</li>
<li>Standard</li>
<li>Express</li>
</ul>
<p>Take into account the new features introduced on SQL Server 2016 SP1 for all versions. More information at <a href="https://blogs.msdn.microsoft.com/sqlreleaseservices/sql-server-2016-service-pack-1-sp1-released/">https://blogs.msdn.microsoft.com/sqlreleaseservices/sql-server-2016-service-pack-1-sp1-released/</a></p>
<p>The -Database parameter is auto-populated for command-line completion.</p>
<h2 id="syntax">Syntax</h2>
<pre><code>Test-DbaMigrationConstraint
    [-Source] &lt;DbaInstanceParameter&gt;
    [[-SourceSqlCredential] &lt;PSCredential&gt;]
    [-Destination] &lt;DbaInstanceParameter&gt;
    [[-DestinationSqlCredential] &lt;PSCredential&gt;]
    [[-Database] &lt;Object[]&gt;]

<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Test-DbaMigrationConstraint -Source sqlserver2014a -Destination sqlcluster
</code></pre>
<p>All databases on sqlserver2014a will be verified for features in use that can't be supported on sqlcluster.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Test-DbaMigrationConstraint -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred
</code></pre>
<p>All databases will be verified for features in use that can't be supported on the destination server. SQL credentials are used to authenticate against sqlserver2014a and Windows Authentication is <br>
used for sqlcluster.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Test-DbaMigrationConstraint -Source sqlserver2014a -Destination sqlcluster -Database db1
</code></pre>
<p>Only db1 database will be verified for features in use that can't be supported on the destination server.<br></p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
